The law is certainly part of it. Now that the major record labels are involved this is even more true. They have their "rules" which are different in every country and require separate negotiation. I expect them to move quickly to try to launch in other countries.

Information on this is understandably thin on the ground. However, it appears that it is only the registration process that checks your country of origin. If you use a proxy to obtain an invitation code you should be able to link that with your current Google Account.

However, as the information is pretty sketchy at the moment I would use caution if you are going to attempt to do this.

Other than that, you will have to wait until Google release the service in the UK.
